Website Buildup

Project is to customized the Magento Theme to our requirement mentioned below. Price for this project will not include the Theme as we will purchased the theme once we decided which one to buy as per your recommendation. Some of the features that needs to be revised on the purchased theme are: 1. We need to add logo to the website. Also, color scheme needs to be changed to match our logo color. 3. We will modify Main Title of the purchased template to our requirements. In addition, content of the website will be changes on all pages. 4. Setting up of the shopping cart in working order. 5. Optimize Magento speed for our store. 6. We need to put site on test server to make sure everything is working such as all links within website. 7. You need to provide us with complete feature list that can be used with the store. 8. We need to setup payment gateway such as Paypal, credit card and debit card. We will start with Paypal payment initially but like to have the credit card payment option also for future. 9. We need to setup shipping of the item such as cost to ship etc. 10. Some of the routine pages that needs to be available such as customer support information, Product return policy, Product categories and details with photos, description and prices. Photo, description and prices will be provided by us. You need to make the photos looks more professional by adjusting the sizes in PHOTOSHOP so that they all looks uniform. We also need to change the background of the photo as required to make them look more elegant. 11. Milestone will be created and payment will be released only after the site is done and working in full. 12. SSL certificate needs to be installed if needed. 13. Implementation of links such as facebook, instagram, blog and other social media sites. 15. Implementation of slider images on the front page. 16. My other question is how much storage is required ? I was thinking of starting with [login to view URL] with $15/month plan that comes with 200MB which in my opinion is good place to start. 15. You need to teach us how to manage the site to change photos and contents for new future products. 17. Website should update the inventory once a product is sold. It should also send a notification via email after any sell on the site.
